Why did this suddenly feel like a test?  Mable's brows furrowed as she tried to recall the beautiful song, humming it uncertainly at first.  She was really trying very hard to remember, but she had only heard it for a moment before Edward stopped.

"It went something like that, I think, it was very happy.  Wait, let me try again.  Whistle this time!"

Somehow, Mable was a nervous performer, even with just once person in her audience.  As she hummed, a little louder now, she ran her hands up and down her braid over her shoulder.  Her eyes were shut firmly in concentration, but it paid off!  The tune was quite similar, she thought!
